Quick tips - Invoice Alignments

Your billing period begins on your anniversary date

When your first iiNet service is activated, your "anniversary date" is set. This is the date your iiNet bills are typically due each month.

The billing period for your iiNet services is also based on your anniversary date (e.g. Billed period: 04 JAN 2017 - 04 FEB 2017). If you add more iiNet services, their billing is aligned to the same billing period.

One exception is iiNet Mobile services, which are typically billed from the 1st to 1st of each calendar month. For more information, please see Mobile Billing Explained.

All iiNet services are billed one month in advance

Recurring or fixed charges such as monthly plan fees are billed in advance, which means they are paid upfront ahead of time.

Variable charges such as phone calls are billed in arrears, which means they are paid after the charges have accrued (after all, we can't know which phone calls you've made until after you've made them!).

When you change plans, you'll receive a credit on your iiNet account for any unused plan fees that you paid in advance. You will then be charged in advance at the rate for your new plan.

How to identify the billing period on your invoice

The Service Details section of your invoice lists all charges along with their respective billing periods.

A) Part Monthly Charge means a partial month has been billed. The dates on the Billing Period will confirm which days you've been billed for.

B) Monthly Charge means a full month has been billed.

Example: Internet service activated BEFORE the invoice is issued

The example below shows the charges for an internet service that was added to an account BEFORE the invoice for that billing period was issued.

A) Service active for 27 days of this billing period

B) Part Monthly Charge for 27 days only

C) Next billing period (one full month in advance)

D) Full Monthly Charge in advance

Please note: If you're trying to follow along with a calculator, it's worth noting that our billing system calculates fees right down to the second. It's unlikely that a service would be activated at exactly 12AM, so while a plan may cost $1.97 for each full day of the year, less than that would be charged for the day a service was activated.

Example: Internet service activated AFTER the invoice is issued

However, it's also possible to add a service to an account AFTER the invoice for a billing period is issued. If this is the case, then charges for that billing period would be delayed until the following invoice.

In the example below, the an ADSL2+ service was activated on 28 July. However, the invoice for that month was already been issued on 24 July, so charges for that billing period must be delayed until the following invoice is issued on 24 August. The invoice issued on 24 August would cover the charges for both the previous and current billing periods, plus one full month in advance.

A) Service active for 10 days of the previous billing period

B) Part Monthly Charge for 10 days only

C) Current billing period (the same month invoice issued)

D) Full Monthly Charge

E) Next billing period (one full month in advance)

F) Full Monthly Charge in advance

Please note: If you're trying to follow along with a calculator, it's worth noting that our billing system calculates fees right down to the second. It's unlikely that a service would be activated at exactly 12AM, so while a plan may cost $1.97 for each full day of the year, less than that would be charged for the day a service was activated.

Why have I only received part of my plan value?

This can happen when you change plans, or activate a new service partway through your billing period.

If you've been billed for a part month charge for your plan, then you'll receive a proportionate part of your plan's monthly value for data, calls or SMS, etc.

For example, if you've been billed for 10 days worth of your new broadband service, you'll receive 10 days worth of its included monthly data.

This is known as "pro-rating", and it means that you'll pay the correct rate and receive the correct value for the exact days you had each plan. Once your next billing period begins, you'll receive the full monthly value at the full monthly price.

Pro-rating does not affect unlimited or all-inclusive allowances, such as our Liimitless broadband data plans. After all, you can't divide infinity!

What happens to fees I've paid in advance if I change plans or cancel a service?

When you change plans or cancel a service, any amount you've paid in advance for that service is credited back to your account.

If you've changed plans, you'll then be billed in advance at the rate for your new plan. Any remaining credit will be used to balance charges on your next invoice.

If you're cancelling one service but you still have others, the credit will be used to balance charges on your next invoice.

If you're closing your account, any remaining credit after your final invoice can be refunded back to your nominated bank account or credit card.
